WATER-GAGE.

' To all whom it may concern:

s, vented certain new and useful Improvements in Water-Gages, of which the-following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in water gages and has relation more particularly to a device of this general character including a transparent sight gage and it is an object of the invention to provide novel and improved means whereby they communications between the gage and the boiler may be cut off automatically upon breaking of the gage.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved water gage'whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure 1 is a view in side elevation of a water gage constructed in accordance with an embodiment of my invention; and

Fig. 2 is a view in front elevation with a portion of the device broken away as illustrated in Fig. 1.

As disclosed in the accompanying drawings Gr denotes a gage-column adapted to have its opposite ends in communication with a boiler in a conventional manner and said column is provided with the try-cocks T of any desired type and preferably three in number. Also in communication with the gage-column G at points above and below the try-cocks T are the fittings F for the water-glass W. Carried by the fittings F are the valves V of a conventional type for controlling the communication between the fittings F and the gage-column G.

The stems of the valves V have affixed thereto the gears 1 in mesh with the gears 2 rotatably supported by a frame A carried Specification of Letters Patent.

Application filed May 25, 1918. Serial No. 236,619.

by the gage-column G. Interposed between the last named. gears 2 is a gear 3 which is rotated through the medium of the spring 4. The gear 3' constitutes a driving element and is normally held against movement through the medium of the brake member M.

Th brake member M' comprises an elongated rod 5 pivotally engaged at a point intermediate its length with the frame A and said rod 5 is provided with a lateral extensionor finger 6 adapted to engagea tooth of the gear 3 for holding the same against movement under the influence of the spring 4. The end of the rod 5 adjacent the gear 3 is provided with a lateral extension 7 adapted to contact with the glass W whereby the extension or finger 6 is maintained 'in operative engagement with the gear 3.

Secured to-the frame A and to the end portion of the rod 5 remote from the extension 7 is a retractile member 8. Should the glass W break, the member 8 serves to swing the rod 5 in a direction to disengage the finger or extension 6 from the gear 3. The gear 3 then rotates under the influence of the sprin 4 and this movement is transmitted throug the gears 2 to the gears 1 and the direction of rotation of the gears 1 is such as to close the valves V. By this means it will be perceived that the escape of water or steam upon breaking of the glass W is prevented. I also find it of advantage to provide the shaft 9 of the gear 3 with an operating member 10 whereby the gears 1 may be rotated in a direction to adjust the valves V into open position and at the same time place the spring 4 under tension.

From the foregoing description, it is thought to be obvious that a water gage constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim:

1. The combination of a gage-column, a water glass in communication therewith at opposite ends and valves for controlling .driving memberfor holding said member "against operation-when the rod. 1s 1n contact with the .glass, and: a spring secured I to '1 .theoppositeend portion of the rodand to the framefor disengaging thelateral extension of: the rod from the driving. member upon breaking of the glass to ipermit the driving member to close the valves.

'2. Incombination with a waterglassand valves for "controlling. communication with the glass at opposite-ends thereof, a driving "member supportedibetween the valves an operatively connected -therewith for closing thevalves, a rodsupportedfor swinging movement "and having one end portion in contact with the;glass,-saidrod being pro- .vided with alateral extension engaging the driving member for holding said member against operation-when the rod is-in contact with the glass and-automatio means for im -.partin'g"swinging*movement to the rod in a- .idir'ection aw ay from the; driving member to release the extension from said member by the frame between the valves and operatively conneotedl therewith for closing the valves, a rod .pivotally supported intermediate its length with the frame and havingan end portion adaptedto contact with the glassysaid end portion being provided with .a. lateral. extension engaging the driving member for holding said. member against operation when the rod is in contactwiththe-glass, and a. spring secured to the opposite endaportion of the rodaandto the frame f for disengaging the lateral :extension ofthe rodfrom the drivingmember upon breaking of the .glass to-permit the driving. member to close the. valves, said driving memberbeing vprovided with means whereby the-same may be operated to open the valves. 1

.In testimony whereof I hereunto affix my signature in the presence of two witnesses.
